Installation Video
Protecta EX Mortar is a castable fire-rated compound, supplied as a dry powder and mixed with water to create a strong, durable seal. Designed for sealing service penetrations in fire-rated floors, it also helps maintain the building’s acoustic insulation and airtightness.
During curing, the mortar slightly expands to create a secure bond around service penetrations and the surrounding structure, ensuring a tight and lasting seal.
Typical applications include:
- Firestopping cables, pipes, and mixed services in floors
- Hospitals, schools, commercial buildings, and technical service areas
The mortar is simple to mix and apply, dries quickly, and leaves a smooth, off-white finish that can be sanded, drilled, or painted if required.
For wall penetrations, we recommend using Protecta FR Board for the most efficient and documented firestop solution.
What is the maximum opening size EX Mortar can be used in?
Without reinforcement, EX Mortar can be used in openings up to 1,200 × 2,400 mm.
With reinforcement bars, larger openings can be cast up to 2,600 × 3,600 mm.
Additionally permitted:
- 1,200 mm width × 12,000 mm length
- ≤ 800 mm width × unlimited length
For reinforced solutions with reinforcement:
- 1,800 mm width × 18,000 mm length
- ≤ 1,500 mm width × unlimited length
All dimensions require the system to be installed according to approved details. See documentation for depth, shuttering, and reinforcement requirements.
Can I reduce the depth of EX Mortar?
Yes, in solutions with a specified minimum depth of 100 mm, it can be reduced by 50 mm if a 50 mm high gypsum mortar cone is formed around the services at a 45° angle.
Note: If this results in a total depth below 100 mm, a mineral wool board must be used as backing.
Which pipes and cables is EX Mortar approved for?
Protecta EX Mortar is tested and approved with:
- Cables and conduits
- Steel pipes
- Copper pipes
- Alupex pipes
- LK Pal Universal pipes
- PVC, PE, and PP plastic pipes
- Composite pipes
- Polybutylene pipes
- PEX pipe-in-pipe systems
See the installation guide for dimensions and details.
Can steel sleeves be used in openings when using EX Mortar?
Yes, openings with or without penetrations may contain a steel sleeve – either embedded or friction-fitted in solid structures. The sleeve must be protected against corrosion before firestopping with EX Mortar.
In which types of structures has EX Mortar been tested?
Protecta EX Mortar has been fire tested in the following structures:
- Concrete and masonry walls
- Gypsum walls
- Concrete and masonry floors
It can also be used in hollow core slabs and ribbed decks.
Is the product resistant to moisture and frost?
The mortar must cure in dry conditions and be protected from frost. In humid environments, Protecta Waterproofer must be used.
